What is the Lemon Test associated with?

The Lemon Test, established in the Supreme Court's decision in Lemon v. Kurtzman, is primarily used to evaluate whether a law or government action violates the Establishment Clause of the First Amendment. The test consists of three prongs, which require that a law or government action must have a secular legislative purpose, must not advance or inhibit religion, and must not result in excessive government entanglement with religion.

This correlation to evaluating secular purposes and entanglement with religion is crucial because it ensures that while the government may engage with religious institutions, it cannot favor or inhibit any particular religion or create a situation where the government is too involved with religious practices. Thus, the essence of the Lemon Test lies in its ability to maintain the separation of church and state, ensuring that any government action is justified by secular objectives and does not lead to excessive entanglement with religious institutions.
